    Due to the commitment to the open source driver development I want to stick with AMD graphics. However, I do need to use the proprietary driver for the time being. I do some gaming, and the open source driver isn't quite good enough for me there yet. My experience with Catalyst on my 6450 hasn't been as good as it is on Windows (graphical issues sometimes, tearing, crappier performance compared to Windows, etc), but I'm still willing to give AMD another chance.

    I'm looking at the new 7750 because of its low power requirements + decent performance. I'm not a heavy gamer, but I'd like to be able to play some recent games (Rage if it comes to Linux, for example) without lag. Graphics quality isn't a huge issue since I usually turn down the eye-candy in games anyway. It seems like the 7750 might be a good option for this. As a reference, if it can smoothly play Quake 4 at Ultra (or high) on 1920x1080 I will be happy. I can run Quake 4 on my 6450, but there's a noticeable amount of jitter and lag. Unsure if this is related to Fglrx or the low-end 6450.

    So in a nutshell:

    - Under $120 (USD)
    - Low power requirements (under 500w)
    - Runs Quake 4 without any lag at 1920x1080
    - Reliable fglrx driver until I can use the open source driver.
    - Small in size (I'm thinking the 6770 or 7770 may be a bit large)

    Any insight is appreciated. I'm a bit curious about the new architecture, hence why I'm considering a Southern Islands GPU.
    I noticed that everyone keeps suggesting fixes, and completely forgets to ask some about the basic computer specifications.
    • Which distribution are you using?
    • How much memory is installed?
    • did you Build the Computer Yourself, or do a full system upgrade? ( Yes or No)
      If the answer is yes, answer the Following:
      • What is the Processor?
      • What is the Motherboard?
      • What type of Memory is in the pc? (DDR3, DDR2, ETC )
      If the answer is No, answer the Following:
      • What is the Vendor? ( Toshiba, Dell, HP, ETC )
      • What is the Model?
      • What is the Model Number?

    All of these questions will provide a much better overall suggestion than a blind suggestion.

    Anyways, I am certain that most of the performance problems is the graphics card, and an easy solution is to try the Radeon HD6670. I know of several gamers who have had excellent experiences on this card where they can play almost all games at maximum settings. I normally suggest video cards that are full size pci cards, however, I do know that there is some low profile cards available, and either of the following cards should handle the job well:

    Sapphire Radeon HD6670 (Low Profile)
    HIS Radeon HD6670 (Low Profile Ready)

      Have you ever even used Linux? I have a feeling you're just trolling.

      OP, I'm in the same boat as you. I have a GT430 in my HTPC at the moment and it works perfectly, but I need a little more power.

      Around the 80 price range ($90 I guess) you have the GeForce GT640 2GB DDR3 and the RadeonHD 7750 1GB GDDR5. Now what sucks here is that the ATi card (using Windows benchmarks as an reference) performs better than the GT640 normally, has a lower TDP (important for quiet / HTPCs) and costs less!

      But then the problem becomes that ATi card support under Linux isn't always great. For example native apps are generally ok, but quite a few games under Wine will simply not work (apparently this is due to the drivers still missing a lot of features that Wine needs to work properly). Also I'm not sure how under-par the raw performance of the Catalyst drivers is, compared to Windows giving their previous track record (where as nVidia's is generally fine).

      So in summary: the 7750 is an all-round better card than the GT640, but may end up being worse / useless due to the drivers (depending on the usage). Pretty rubbish situation really.

      EDIT: To add to this, which I forgot earlier, is that the Catalyst drivers are also normally lagging behind XOrg and Kernel updates, sometimes by several months, so if you're running an up-to-date distro, you may find that either you can't update your Kernel or XOrg for some time due a Catalyst incompatibility, or that you'll update them and suddenly find the driver doesn't work anymore. This has been my biggest annoyance on my ATi/AMD graphics hardware.

        Maybe in a perfect world if AMD lived up to everything they've promised you'd be right. In the real world I use Nvidia though. I get good 3D acceleration and great video playback.

        This is my GT520 running a Quake time demo with the Darkplaces engine

        Video Mode: fullscreen 2720x1024x32x0.00hz
        969 frames 12.9987194 seconds 74.5458046 fps, one-second fps min/avg/max: 50 74 81 (74 seconds)

        Numbers don't lie.

          It seems they do, as nobody sells 2720x1024 screens. Your numbers claim that to be the fullscreen res.

            With a little thought, it seems he's running 2 monitors (side by side) at 1360x1024 resolution (1360 x 2 = 2720). Makes sense.

              It seems the original poster has been living under a rock.

              1. Catalyst has always been problematic on Linux and will stay that way - I switched away from ATI (partly) because I had to wait for a new release of Catalyst (or two) whenever Ubuntu switched to a new X server. And Ubuntu isn't all that cutting edge even.
              2. The open-source driver will never be usable for gaming. Ok, maybe when AMD releases Radeon 12770, your 7770 will work better using the open source driver, because AMD would have dropped support from Catalyst 3 years before.

              But if you don't care about a usable card and just want to support OSS, then your choices would be ok.

                That you can run Quake in multi screen.

                    That if you use a wide aspect ratio screen along with a 3x4 then your crosshairs don't end up between the monitors. I like it that way too! One thing AMD does have going for it is they offer more 3 screen solutions than Nvidia does. Or so I've heard, I'm not the worlds biggest AMD fan so I don't stay that up on it.

                      1. Yep, I am a long time NVIDIA user who decided to give AMD a go after seeing some improvements with the open source stuff. I tried to make do with Fglrx until OSS catches up, but it's just nowhere near the reliability of NVIDIA for me.

                      2. Depends, but overall true.

                      I didn't buy the GPU after (forgot about this thread until it hit the front page), and will be grabbing a mid-range NVIDIA card soon to replace the 6450 so I can go back to forgetting that my driver exists. Maybe in a few years I'll give AMD a go again; I won't be bothering after the consistent Fglrx issues I've been having. I still recommend AMD cards for non-gamers, though... the open source driver is great overall for 2d, media playback, and basic 3d.

                        I'm looking for the best "no-additional-PCIe-adapter-required" card right now and as far as I can tell that's the GT640, but the 640 gets killed by the 7750 which is the same price.

                        Is there another, better nVidia card that I'm missing, or will it be a case of waiting for the GT640 with GDDR5? (and why is this not already out?)

                          Hm, right, I discounted dual screens because 1360x1024 monitors aren't sold either. Pretty weird setup you got there, gaming on two different-sized monitors.

                            Googling it gives a bajillion wallpapers so it's apparently common, but I agree that it seems like a really weird resolution.

                              As kano mentioned before, the video card you chose to begin with is not meant for games. That card was best suited for basic Desktop usage without games. Even phoronix's own reviews show that the Radeon HD6550D[2] performs on average two times faster than the Radeon HD6450 [1].

                                Yeah, wouldn't it be just great to have to shell out twice as much for half as good hardware, competition is such an overrated concept for us consumers.

                                Anyway...

                                Fairly silent once the fan control kicks in, shorter than reference cards, performs great for the price.
                                Can't comment on XvBA since I stick to SMplayer with GL output.
                                ALSA is having problem with the HDMI output at the moment, if that's important to you.

                                By the way Newfie, what does the rest of your rig look like?
